초록

해상 유통되는 유해액체물질(NLS)의 유출사고대비 물질군 선정을 위해 596종의 NLS를 대상으로 위해성 DB를 구축하고 우선 순위 선정시스템을 통해 전체 우선순위를 선정하였다. 우선순위 목록을 바탕으로 2014-2015년 해상유통물질 158종을 추출한 뒤 물질군 구분 기준을 적용하여 0~3순위의 4개 물질군을 제시하였다. 국가차원의 NLS 유출사고대비를 위해서는 물동량 및 유해성이 높은 0~1순위 물질군의 집중관리와 함께 2~3순위 물질군의 정보 구축작업이 지속되어야 한다. 항만별로는 NLS 유통 유형이 다르므로 각 항만의 물질별 유통특성을 파악한 뒤 0~1순위 물질군 위주로 관리하는 것이 효율적일 것으로 판단된다. 또한, 동해남부권역(울산, 부산), 남해중부권역(광양, 여수), 서해중부권역(평택, 대산, 인천)을 NLS 사고대비를 위한 특별관리구역으로 지정하여 해상유통되는 NLS 의 감시 감독을 강화하고 방제 장비, 자재 및 약제를 집중 배치해야 할 것으로 판단된다. 향후, 위해성 DB의 구축과정에서 나타난 위해성 정보 부재 물질들의(만성독성) 지속적인 생산 및 보완이 필요하며, 특히 수생태 독성의 경우 해양생물종을 대상으로 한 자료 생산 및 확보가 지속되어야 할 것이다. 또한, 해상 HNS 사고 관리를 위해서는 HNS 해상유통에 대한 정보를 확인할 수 있는 시스템이 조속히 구축되어야 한다.

This study prioritizes Noxious Liquid Substances (NLS) transported by sea via a risk-based database containing 596 chemicals to prepare against NLS incidents. There were 158 chemicals transported in Korean waters during 2014 and 2015, which were prioritized, and then chemicals were grouped into four categories (with rankings of 0-3) based on measures for preparedness against incident. In order to establish an effective preparedness system against NLS spill incidents on a national scale, a compiling process for NLS chemicals ranked 2~3 should be carried out and managed together with an initiative for NLS chemicals ranked 0-1. Also, it is advisable to manage NLS chemicals ranked 0-1 after considering the characteristics of NLS specifically transported through a given port since the types and characteristics of NLS chemicals relevant differ depending on the port. In addition, three designated regions are suggested: 1) the southern sector of the East Sea (Ulsan and Busan); 2) the central sector of the South Sea (Gwangyang and Yeosu); and 3) the northern sector of the West Sea (Pyeongtaek, Daesan and Incheon). These regions should be considered special management sectors, with strengthened surveillance and the equipment, materials and chemicals used for pollution response management schemes prepared in advance at NLS spill incident response facilities. In the near future, the risk database should be supplemented with specific information on chronic toxicity and updated on a regular basis. Furthermore, scientific ecotoxicological data for marine organisms should be collated and expanded in a systematic way. A system allowing for the identification Hazardous and Noxious Substances (HNS) should also be established, noting the relevant volumes transported in Korean waters as soon as possible to allow for better management of HNS spill incidents at sea.
